Juice processing by non-thermal technology has been extensively studied, aiming at microbial inactivation and quality improvement. However, the knowledge about possible toxic effects that those technologies can produce in foodstuffs due to production of reactive oxygen species is still unknown. In this study, sapota-do-Solimões juice processed ultrasound (2, 6, 10 min) was evaluated a toxicity ...

This work aimed to develop a methodology for marking Artemia with different markers and evaluating their passage rate digestibility in Lophiosilurus alexandri larvae of ages. In the first phase, nauplii were marked 28 h after hatching chromium oxide, titanium dioxide NANOLIPE®. Contact times 30, 60, 90 min at concentration 500 mg/L. Titanium had higher than other markers. The did not differ sig...

In this study the optimal amount of enriching Artemia franciscana with a synbiotic combination of Pediococcus acidilactici and fructooligosaccharide (FOS( was investigated. The experiment was conducted in a completely randomized design in ten treatments: multi-level probiotics P. acidilactici (1×109, 1×108 and 1× 107 CFU per L) and mul...

Bromide is a common ion found in freshwater and marine systems. Although normally at relatively low concentrations, higher levels may occur point-released wastewaters as well nonpoint runoff from agricultural or industrial locations where bromide compounds are used biocides disinfectants. In this study, the potential toxicity of NaBr saltwater environment was studied using brine shrimp, Artemia...

The pen shell, Pinna nobilis L. is critically endangered by the spread of a haplosporidan parasite. Stable isotopes have been shown an association with dietary assimilation, trophic level, and body condition, can provide valuable information for ex situ conservation breeding. In this context, aim study was to investigate nutritional status individuals using ?13C ?15N patterns across shell tissu...

We conducted two laboratory experiments to evaluate the dietary effects of phytoplankton and zooplankton on larval survival, duration growth amphidromous atyid shrimp Atyopsis spinipes. In first experiment, commercially preserved or cultured Tetraselmis sp. rotifers were used rear larvae. second feed larvae for 17 days after hatching, which effect supplementing their diet with Artemia nauplii w...
